made it thur a day of server down 270 + tasks reported when server came up.
with plenty in cache. First time ever. I also go a few astopusle wu ( 155 min runtimes once cpu freed up) Let the good times roll.

Ok, I had a quick look at everything you posted, your PC with the 520 and even the front page of your website and:

a) I'm not buying the whole "caveman" thing:)
b) I'm no Lunatics expert but maybe it's because you haven't installed the apps for CPU? It could be you have, and just haven't returned any results yet but CPU lunatics isn't showing up on the application details page of your 520 PC.

Edit:
...machine ID 'lepc'...
Not importartant but just so you know, the names of your PCs (and a bunch of other more personal info like IP addresses and other stuff) are only shown to you. In other words, no-one else can see the names of your PCs even if you wanted them to:)

@Snowmain

that is a very interesting list ;) thanx

in the next some weeks my Nvidia-GT630 get a new friend that is not in the list.
im courious about the WU's/$ :D

Well, no, I haven't installed the Lunatics apps for the CPU -- does that matter? (I guess I could install them and see what happens...) I'm running WU's from projects that don't support GPU's in the CPU, but not any from projects that support the GT 520. I'm currently running SETI, Einstein and Milkyway WU's in the 520 (and NOT in the CPU).

This brings up another question: Since there is no Lunatics NVIDIA GPU app for Astropulse (as of yet...), will my machine run GPU Astropulse WU's using the standard SETI app, or do I need to add something the the app_info file? And if so, what? The answer may be out there somewhere, but a search here and on the Lunatics site hasn't turned it up...

@ The Chosen.....and everybody else.


For my 2 cents the 229$ on the gtx 570 is the price performance Delta.
My hope is that Sept 16th when the newest GTX 650 and 660 come out it will push down the price of gtx 570. Here's hoping.

Finding power consumption #'s on the mobile processors was very difficult. Since the likelyhood of them being used is so low when I foujnd a number I didn't look any further...so they very well could be wrong( as any of these numbers could be wrong).

yes, once you enable AP tasks via your web preferences, your host should eventually download the stock nVidia OpenCL Astropulse binaries, and tasks will of course follow when they become available. you really only need an entry for it in the app_info.xml if you want to run multiple tasks in parallel/increase GPU utilization/decrease CPU utilization/mitigate GUI lag/etc.

Thanks for the reply. The stock binaries haven't appeared yet, but maybe I need to de-select AP, update, and then re-select AP.

This brings up another question -- where can I find info on what all can be done via settings in the app_info.xml file??? Can multiple stock AP tasks be executed in the GPU? I didn't think that was possible...

perhaps it isn't supposed to download the executable and the associated files until new AP tasks are actually ready to be sent to your host...i really don't know. i would try manually updating the project from within BOINC before i try deselecting and re-selecting AP tasks in the web preferences. worst case it tells you that AP tasks aren't available at this time, and you'll get the binaries when tasks become available.

come to think of it, i'm not entirely sure if it would even be worth it to try to run more than a single task at a time on a GT 520. your card may have enough VRAM to run more than one task at a time, but a single task just might come close to maxing out your GPU utilization. really there's only one way to find out - run a single AP task, and then try two at a time. if they finish in less than twice the run time of the task that ran by itself, then your card can benefit from multiple tasks at once. rinse and repeat...although i can tell you right away that the 1GB of VRAM on GPUs like yours (and even my otherwise much more powerful GTX 560 Ti's) will not be enough to run 3 tasks in parallel...not without over-utilizing VRAM and increasing run times. at any rate, here's how the AP nVidia section of my app_info.xml reads:

<app_info>

<app>
<name>astropulse_v6</name>
</app>
<file_info>
<name>AP6_win_x86_SSE2_OpenCL_NV_r1316.exe</name>
<executable/>
</file_info>
<app_version>
<app_name>astropulse_v6</app_name>
<version_num>604</version_num>
<avg_ncpus>0.04</avg_ncpus>
<max_ncpus>0.2</max_ncpus>
<plan_class>cuda_fermi</plan_class>
<cmdline></cmdline>
<coproc>
<type>CUDA</type>
<count>0.5</count>
</coproc>
<file_ref>
<file_name>AP6_win_x86_SSE2_OpenCL_NV_r1316.exe</file_name>
<main_program/>
</file_ref>
</app_version>

</app_info>

the <count>n</count> statement is the one that controls the number of tasks running in parallel, where n=1 corresponds to 1 task, n=0.5 corresponds to 2 tasks, n=0.33 corresponds to 3 tasks, and so on and so forth...

Well, I know about <count> and I finally found some info on <flops>, but there is stuff in there that I don't entirely understand (for example, what's <avg_ncpus> mean?). It would be nice if the parameters in the app_info file were documented someplace...

I am currently running two SETI tasks in the 520 -- they appear to complete in somewhat less than twice the time for a single task, so It looks like I am coming out ahead. GPU-Z shows 99% GPU Load, 74% Memory Controller Load, 466 MB Memory Used and GPU Temp of 79 deg C when running two SETI enhanced tasks in parallel. GPU Load was 92 - 93% for a single task. Interesting that even under 99% GPU Load, I don't see any effect on the display with GPU tasks running.

But it would be nice if I could get Fred's test program to run on my machine...

hmm...it appears you have some room to push. i could have sworn that 3 simultaneous tasks would require more than 1GB of VRAM, but 2 simultaneous tasks on your GT 520 appear to be using only 466MB...i must be mixing up SETI w/ some other project as far as VRAM consumption is concerned. so i suppose you could try 3 simultaneous tasks to see if they finish in less than three times the run time of a single task by itself.

If you look at the numbers posted in this thread, you'll see that for most video cards 2 is the number.
Only highend cards get any benefit from 3, on most cards you end up doing less work.

yeah, that's what i originally thought and seemed to remember...then i saw that the SETI tasks weren't consuming as much VRAM as i thought they were. then i started to think about all the other projects i'm involved in, and figured i might be confusing SETI's VRAM requirements w/ that of another project...and so i started to second guess myself. but as i mentioned in a previous post, i was only able to run 2 Multibeam tasks at a time on either of my GTX 560 Ti's.

For those who use nVIDIA cards that have high temp readings you can adjust the cooling fan speed using the following software from nVIDIA:

http://www.nvidia.com/object/nvidia-system-tools-6.08-driver-th.html

This will not negate the use of 306.02 beta driver for you cards. Works great
My cards went from 70c to 53c in a matter of min. Fan speed max is 70 %.

Or you could just download MSI Afterburner and design you own custom fanspeed vs. Gpu temp Curve.

Max fan speed 100%.

Besides you need a graphics cards with CHL8318+uP6262 voltage regulators.

yes, it'll work on just about any system. nevertheless, some people occasionally have trouble with it, and have to resort to an alternative method of GPU monitoring. so thank you for posting a link to the nVidia System Tools w/ SEA Support, as i'm sure some folks will find it to be a viable alternative to MSI Afterburner.

Well, that does not appear to be the case as I received the following message:

SETI@home: notice from server
your app_info.xml file doesn't have a usable entry of AstroPulse V6

So obviously, I need to add entry(s) the the app_info file -- but what?? I think that I will start a new thread on this and see if anyone can help...
